  • A: Directions for Use It is a violation of Federal law to use this product in a manner inconsistent with its labeling. DO NOT USE ON HORSES INTENDED FOR SLAUGHTER Feed the recommended dosage of Farnam® SimpliFly® Feed-Thru Fly Control to each horse separately to make certain he receives his full portion. This product should be fed top dressed on grain or mixed with the horse's total ration to provide 6.8 mg of diflubenzuron per 100 lbs. of body weight. For an occasional finicky eater who does not accept new feeds readily, mix this product with sweet feed or grain ration. Start feeding Farnam® SimpliFly® Feed-Thru Fly Control early in the spring before flies begin to appear and continue feeding throughout the summer and into the fall until cold weather restricts fly activity. This product contains an insect growth regulator which prevents the development of house flies and stable flies in the manure of treated horses, but is not effective against existing adult flies. In some cases, supplemental fly control measures may be needed in and around paddocks and buildings to control adult house and stable flies which can breed in other decaying vegetable matter or silage on premises, or that migrate in from other areas. Farnam® SimpliFly® Feed-Thru Fly Control should be used as part of an integrated pest management program aimed at reducing fly populations in the horse's environment. Consult your retailer for program recommendations. In order to achieve optimum fly control, this product should be used in conjunction with other premise and on-animal products as well as good management and sanitation practices. DAILY DOSAGE 300-500 lb. Horse, Pony or Miniature Horse Feed 2/5 oz. per horse per day. 500-700 lb. Horse or Pony Feed 3/5 oz. per horse per day. (One measuring cup filled to the red line.) 700-900 lb. Horse Feed 4/5 oz. per horse per day. 900-1100 lb. Horse Feed 1 oz. per horse per day. 1100-1300 lb. Horse Feed 1 1/5 oz. per horse per day For larger horses over 1,300 lbs. of body weight or draft horses, feed an additional 1/5 oz. for each additional 200 lbs. of body weight.

This product used in conjunction with diatomaceous earth and using our fans does an excellent job of keeping the fly population under control in our barn.
